Stupid Critters

Something stole the cherry tomato in the picture several posts ago.  So mad!  And there appear to be some bugs I can't see nibbling on the leaves of my cucumbers and pepper plants.  The rest of my garden seems fine...ish.  Found a spot where it looks like a squirrel must have been digging a little hole.  Something regularly plucks the beginnings of strawberries off my strawberry plants.  And this evening I found a blueberry in with the carrots.  I've tried chili powder.  I don't have any coffee grounds.  Mom suggests moth balls.  Don't know yet what else to do except put up fence I can't get through either.  So obnoxious.  I'm going to Lowe's tomorrow.  Hopefully someone there can point me toward something to at least stop the bugs.
